RC racing cars are remote-controlled models popular among hobbyists, available in electric (LiPo/NiMH) or nitro/gas types. Key features include size scales (1:10 to 1:5), drive systems (2WD/4WD), and car types (touring, buggy, crawler). Components cover chassis, motor/engine, control systems, and maintenance tips like cleaning, lubrication, and battery care. Beginners should start slow, practice controls, and prioritize safety. Upgrades and community engagement enhance the experience.
